Technical Services

Hands-on remote engineering support for servers, container environments, cloud platforms and business branch networks.

Linux & Server Infrastructure

Server deployment, configuration, migration and troubleshooting.

Whether you are setting up a new production server, migrating between cloud hosts or hardening an existing system, we configure Linux environments for stable, secure operation.

Included Capabilities and Configuration

  • Ubuntu, Debian, AlmaLinux, Rocky Linux and CentOS/RHEL support
  • High-performance Nginx, Apache and Caddy reverse proxy and load balancing
  • Automated Let’s Encrypt certificate renewal and DNS configuration, including Cloudflare
  • SSH hardening, fail2ban brute-force protection and UFW/iptables firewall policies
  • Kernel tuning, abnormal disk-usage recovery and log-based troubleshooting
  • Root-cause analysis and practical remediation recommendations
Deliverables
  • A stable server configured to the agreed requirements
  • Firewall and basic security configuration review
  • Basic operating notes and secure credential handover

Docker & DevOps

Container deployment, CI/CD, reverse proxy and application infrastructure.

Standardise and simplify application delivery and operations. We package services into maintainable Docker stacks, build reliable deployment pipelines and configure ongoing monitoring and alerts.

Included Capabilities and Configuration

  • Dockerfile layer and image-size optimisation using multi-stage builds
  • Docker Compose service dependencies and network topology
  • Automated GitLab CI and GitHub Actions integration and deployment pipelines
  • Service monitoring and alerts using Prometheus, Grafana or Portainer
  • Scheduled off-site backups for PostgreSQL, MySQL and Redis to S3/R2
  • Rolling updates, health checks and restart policies designed to minimise downtime
Deliverables
  • Version-controlled Compose configuration and Dockerfiles
  • A tested automated deployment pipeline
  • Automated backup scripts with recovery verification

Cloud Infrastructure

Cloud server setup, migration, DNS, SSL and infrastructure configuration.

Plan and optimise resources across AWS, DigitalOcean, Hetzner, Linode, Vultr and similar providers. We handle private cloud networking, instance sizing, cost control and carefully planned migrations.

Included Capabilities and Configuration

  • VPC private networks, security groups, subnets and Elastic IP configuration
  • Business migrations to the cloud and zero-downtime cross-provider migration planning where feasible
  • Object storage integration with S3 or Cloudflare R2 and static-asset acceleration
  • CDN configuration and edge-cache rules
  • Cloud resource and billing review to reduce unnecessary monthly spend
Deliverables
  • A cloud environment aligned with the agreed budget and security baseline
  • A migration cutover plan with downtime-risk controls
  • A DNS and domain migration checklist

Network & Site-to-Site Connectivity

Site-to-site connectivity, IPsec, WireGuard and network troubleshooting.

Securely connect offices, branches, remote staff and private cloud networks. We configure modern encrypted tunnels and diagnose persistent latency, packet loss and overlapping subnet or routing conflicts.

Included Capabilities and Configuration

  • Site-to-site IPsec VPN connectivity between routers and firewalls
  • High-performance WireGuard mesh and remote-access configurations
  • VLAN segmentation, static or dynamic routing across subnets, and NAT policies
  • Firewall configuration for pfSense, OPNsense, MikroTik, UniFi and Linux iptables
  • Encrypted branch-to-head-office connectivity planning
Deliverables
  • A stable encrypted link with automatic reconnection
  • A network topology and subnet plan
  • Device configuration documentation and backup files

SD-WAN & Multi-Site Networking

Multi-site connectivity and business network infrastructure.

As part of our network engineering services, we plan and implement software-defined wide area network (SD-WAN) solutions that connect branches, warehouses and cloud systems without relying on expensive leased lines.

Included Capabilities and Configuration

  • Multi-WAN aggregation and rapid automatic failover
  • Self-healing encrypted overlay networks across different ISPs
  • QoS prioritisation for core business traffic such as ERP and database systems
  • Centralised monitoring and connectivity analysis across distributed sites
Deliverables
  • SD-WAN architecture design, configuration and implementation
  • A primary/backup link failover test report
  • A concise expansion guide for adding future branch sites
